**onsemi** · Diodes - Fast Recovery Rectifiers · TO-247-2

FFH75H60S from onsemi, in a TO-247-2. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Cathode | passive | Diode cathode, rated for 600 V peak repetitive reverse voltage (VRRM) and 75 A average rectified forward current at TC = 105°C. |
| 2 | Anode | passive | Diode anode, forming the forward current path with a non-repetitive peak surge current rating of 750 A (60 Hz single half-sine) and an operating junction and storage temperature range of −65 to 175 °C. |
